| Recently bought a 187 Mini 14 from my uncle. The first thing I changed on it was the stock which is now an ATI Strikeforce Stock with a full aluminum upgrade set (Rails and buffer tube). I'm looking for way to make it more accurate at 100 yards as it currently is making 1.5" 3-shot groups at 25 yards. My current plans are to install a recoil buffer and a tunable gas block, and later on install a Mo-rod and a muzzle brake (added weight on the end of the barrel) with an integral barrel tuner. Is there anything else I should do to help the accuracy of my Mini? I'm not changing the stock back so please don't waste your time with that one. |

Have you tried to use different weight bullets? My 183 series hates 55 and 62 gr but it will put 50 gr at a 1.25" at 100 with open sites off bench. Fussy as hell with ammo. Other than that I would suggest maybe looking at accuracy internationals website and see if anything they offer tweaks your interest. They do quite a few new barrel styles that all offer pretty good accuracy out of the mini.

Fussy as hell with ammo. Yeah, mine is a fussy eater too. She shoots 68+ gr without any issues, but 62 gr throw wide groups and 55 gr likes to keyhole. Now I'll probably pick up a box of 50 gr to see if it work at all. I got the AI tunable gas block and high power recoil spring and it made a huge difference. |

Joe I have had GREAT luck buying 50 gr ammo from wal mart. Federal ammo in white box. JHP. Not very nice for hunting but they have no key holed from my rifle and like I said, groups arent bad for an old mini. Let me know how you roll with yours. Some day I would love to have one w a barrel that ate heavy ammo. Something short and NASTY like.

Just seems illogical that the lighter (and presumably shorter) bullet would work better with that barrel twist, either way i'll try it out sometime. |

Just found this about 1-7 twist Mini-14's on THR, http://www.thehighroad.org/archive/index.php/t-67087.html
"The serial numbers are approximately: 1989: 185-56000 or for the Ranch Rifle: 187-84000 1994: 186-35000 or for the Ranch Rifle: 188-75000'' The source was was quoted as a Ruger web page. |
